Which of these samples of H2O would have the lowest density?
A
a sample at 200 degrees C
B
A sample at 95 degrees C
C
a sample at 40 degrees C
D
a sample at-20 degrees C
Explanation: 

Detailed explanation-1: -Water’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes: the water molecules are pushed farther apart compared to liquid water.

Detailed explanation-2: -UKAS ISO/IEC17025 and ISO Guide 34 certified, density: 0.9982 g/mL at 20 °C, density: 0.9970 g/mL at 25 °C.

Detailed explanation-3: -Hence, gases have the least density.
